i had dropped my computer a couple days ago and the screen was slightly darker. i figured it was either the inverter or the bulb. so i disassembled the screen, checked the bulb and it didnt seem bad, and put it back together to test it .now only a small strip at the bottom of the screen has normal lighting. could it be those little pieces of plastic at the back of the LCD? possibly something was knocked loose originally and since i tried to put it back together, i might have partially fixed the problem?
